Which rheumatic disease is associated with MR according to the material?

• A. Ischemia
• B. MVP
• C. Bacterial endocarditis
• D. RHD

Answer: (D)

Rheumatic heart disease can damage the mitral valve enough to cause regurgitation. The inflammatory process from rheumatic fever often affects the mitral leaflets and their supporting structures, leading to thickening, chordal shortening, and commissural fusion. These changes prevent the leaflets from closing properly in systole, so blood leaks back into the left atrium, producing mitral regurgitation. Other options aren’t the rheumatic valve disease described here: ischemia causes MR from papillary muscle dysfunction or rupture; mitral valve prolapse is a degenerative process; bacterial endocarditis can cause MR from vegetations. The question specifically points to a rheumatic process, i.e., rheumatic heart disease.
